GRAIN-BINDER ELEVATOR.k

- SPECIFICATION forming part of Letters Patent No. 337,643, dated March 9, 1886,

Application filed October 22, 1884. Serial No. 146,203. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM M. WHITING, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Grain-Binder Elevators, of which the following is a specification, reference being had to the accompanying drawings.

My improvements relate more particularly to that class of grain-binding harvesters in which the grain is taken from the platform and carried over the main wheel by elevatorbelts, and by them delivered to the binding mechanism situated above and outside of the main wheel; and it consists ina fixed shield or guard, which covers the rear edge of the lower elevator-belt and prevents entanglement of the grain with the rollers by which it is driven.

The greatest utility of my invention is developed when the machine is working in longer grain than that for which it was designed, though it is a useful and desirable feature at all times in so far as it prevents dirt, loose straws, or any foreign substance from getting under the edge oi' the belt and between it and the rollers, where it would pack and accumulate to an injurious extent. and could only be dislodged by stopping the machine and removing the belts from the rollers-an operation lconsuming much time and detracting greatly from the value of the machine where it has to be often repeated in the field.

In the accompanying drawings,which show so much ot' a harvester as is necessary to illustrate my invention, Figure lis a perspective view of a portion of the elevator-frame of a harvester, showing the elevator and platform belts partly broken away and their relative positions to each other, and also the application of my improved guard to the rear edge of the lower elevator-belt. Fig. 2is a transverse section through the upper rolls and portions'ot' the elevator-belts; and Fig. 3 is a longitudinal section of the same on the line 3 3 of Fig. 2, as seen by an observer standing above and on the grain side of the elevator and looking in the direction of the arrows.

The elevator-standards A, one only of which is shown, support in suitable bearings the rollers B B,for the upper e1evator-belt,B2, and rollers C C', for the lower elevator-belt, C. These belts are carried upon and driven by the rollers, in the usual manner, in the direction shown by the arrows, taking the grain which is delivered t0 them by theplatform-belt D and carrying it up between their adjacent surfaces,and deliveringit upon the pitch-board or biudingtable E within easy reach of the packing devices of any suitable binding mechanism. A guard or apron, F, of canvas or metal, xed at one of its edges f to the elevator-standard, overlaps and protects the rear' edge of the lower elevator-belt. It may be fastened at its lower end, f, to a part of the elevator-frame, or a special block or projection attached to the frame for this purpose; but if it is made of metal this attachment may be dispensed with, the edge connection alone being sufficient to sustain it in position. At its upper end, f, it curves over the up-l per roller7 and isatlached t0 111e pitch-board, as shown. Various other methods ot' attaching and sustaining the guard will readily occur to any skilled person, the one I have shown being the rst to suggest itself and the easiest ot' illustration, though I do not wish to confine myself to it.

The carrier-slats are shown as projecting under the guard; but they' may advantageously be shortened and the guard permitted to lie close to or even against the surface of the belt.

When the machine is handling longer grain than it is designed, or, in other words. grain longer than the space between the elevatorstandards, the heads must necessarily bend back and drag against the rear standard. rIhis causes a considerable massing of material at the rear edge of the belts,with a strong tendency for some of it to nd its way around the edge of and under the belt, where it becomes engaged with and wraps upon the rollers.

I have in practice experienced so much trouble from this source that without any Having thus described my invention, I

claim as my invention-f In a, harvesting-machine, the combination, In testimony whereof I affix my Signature in with the elevator-belts, of n fixed guard lo- Y presence of two Witnesses. cated between the belts and attached to the frame of the elevator and overlapping the w ILLIAM M WRITING 5 rear edge of tl'le lowex1 01 gralwcarl'ying belt vWitnesses:
